'The noise is like BRRRRRRR, like a plane coming very low and [dropping] bombs over your head. I can't sleep.'—Louise Robin, 74, from Cartierville

But there is no perfect solution for plane noise given Trudeau International Airport's proximity to the city, Cherry said Thursday at the authority's annual general meeting in Montreal.

Hundreds of residents from boroughs in northwest Montreal, Laval and Lachine picketed the meeting, demanding restrictions on night flights and asked that certain paths be rerouted.

Protesters then piled into the meeting room and monopolized question period with queries about the flight paths and noise pollution they say is unbearable.

The Aéroports de Montréal (ADM) has been experimenting with new flight paths since September 2006, trying to divert larger jets leaving or departing from Dorval between 11 p.m. and 7 a.m.

One new path crosses Montreal's northwest region, where residents in Cartierville, Ahuntsic and Laval say the planes fly too low and make unbearable noise.

The flight path is under committee review and will only be approved if certain criteria are met, including noise reduction, number of people affected and plane altitude, Cherry said.

"If we're able to do this, we'll continue," he said. "And if we're not able to do it, we're gonna have to put an end to it, 'cause it's not meeting what we set as the criteria at the beginning."

The planes should not be flying any lower than 762 metres, he said. A proposed flight path over Lachine will also be reviewed.

Residents affected by the flight path near Dorval say their health is being affected by the incessant sound of planes taking off at night.

"The noise is like BRRRRRRR, like a plane coming very low and [dropping] bombs over your head," said Louise Robin, 74, a resident in Cartierville's Saraguay neighbourhood. "I can't sleep."

"What are they giving me … five hours of sleep, four hours of sleep? Our areas have never had planes. All of a sudden we have these monsters over our head," said Robin, who attended the meeting on behalf of 280 resident in her seniors' residence.
